Wipe free space

I take in old laptops and replace the operating system with Linux. These are given away to kids who need them. I have a machine which is 32 bit and I’ve put MX Linux on it, replacing Windows. How do I go about wiping the free space to protect the privacy of the donor please?

Thanks for your help…..

Bleachbit.

(Also there's a way (dd) to do that manually, if you like).

Thanks, I’ll take a look at that. Is Bleachbit already in the MX Linux distro?

Not ootb but can be installed either with cli or MXPI.

However the one in the repo may be a bit older. You can (as I always do with new releases) right-click on the downloaded deb file: "Install Deb Files".:

If you fire up gparted, with that remove all the partitions, then format the one thing to ext4, and then start setting up for a new install, I wager that is sufficient.

Yes but (re)formatting doesn't really wipe data (still recoverable).. hence such methods to "overwrite" data: either using zeroes or 1/0 randomly.

Nobody is going to pay money or make the effort to recover the data of a laptop that has MX installed on it. Way too much trouble and no payoff.

There was a live cd I used to use for secure wipes.

I think this is it. https://dban.org/
